Frequently Asked Questions

The Hedra offers far more flexibility with independent voice control, MIDI integration, and complex rhythmic possibilities beyond basic interval shifting.
It's highly recommended—even slight tuning discrepancies can muddy the sound with multiple voices; Micro Tune ensures pristine harmonic accuracy.
While designed primarily for guitar, the Hedra's adjustable range and MIDI capabilities make it usable with bass, though you’ll need to experiment with settings to find optimal results.
